Hi there, serghio. 

Allow me to share some information about connecting Power BI to QuickBooks Desktop (QBDT). 

Currently, the option to connect Power BI to QuickBooks Desktop is unavailable. As a workaround, you can utilize a third party that integrates with QBDT.

You can visit the QuickBooks Apps site and look for an app that meets your business needs. Another way is by going to the Apps menu on the left panel. 

In case, you'll want to personalize and add specific info to your invoice and other form styles in QuickBooks Desktop To know more about it, you can check out the detailed steps in this article: Use and customize form templates.

Please don't hesitate to get back here if you have clarification about this. I'm just around the corner to help. Have a good one and keep safe.
